Abstract: An image processing method for a unmanned aerial vehicle includes: aligning a subject matter by a camera of the unmanned aerial vehicle focusing on the subject matter at A first time, and recording images information in a focus flame as first reference pattern, presetting a separation distance of automatic movement of the unmanned aerial Vehicle, focusing on the subject matter at a second time, and recording image information in the focus frame as a second reference pattern, synthesizing a three-dimensional reference pattern of the subject matter according to the first reference pattern and the second reference pattern, automatically traversing images in whole camera aperture by the focus frame when the unmanned aerial vehicle detects interrupt of controlling signal, and comparing with the three-dimensional reference pattern.
